Robust Construction and Specifications

Durability is at the core of the Mid Frame Trailer's design. It features a welded steel tubing frame that provides superior structural integrity compared to bolted alternatives. The heavy-duty axle is equipped with roller bearing hubs and a leaf-spring suspension system, which absorbs road shock and vibration, protecting the sensitive internal components of your welding machine during transit. With a net payload capacity of 1,424 pounds (646 kg) and a gross axle weight rating of 1,605 pounds, this trailer handles the weight of compatible welders with ease.

Highway Ready and Compliant

This unit comes fully equipped for legal highway use right out of the package. It includes durable fenders to protect your equipment from road debris, a complete lighting kit for visibility and compliance, and a standard wiring harness. The trailer connects via a standard 2-inch (50 mm) ball hitch, making it compatible with most standard work trucks and service vehicles. A convenient jack stand is included, allowing for easy hitching and unhitching, as well as keeping the trailer level when parked.

Dimensions and Compatibility

The trailer's design is compact yet stable, with a track center of 46 inches and a road clearance of 8 inches, allowing it to navigate various terrains. The bed height sits at a convenient 19.5 inches, facilitating easier loading and maintenance access. Weighing in at a net weight of 181 lbs, it is manageable yet substantial enough to provide a solid towing experience. Trust the Miller 301438 to deliver your power source wherever the job takes you.
